Hi There People!

Page One.

<A HREF="page_2.php<?print("?number=1");?>" TARGET="iframe1">Link</A><BR>
<A HREF="page_2.php<?print("?number=2");?>" TARGET="iframe1">Link</A><BR>
<A HREF="page_2.php<?print("?number=3");?>" TARGET="iframe1">Link</A><BR><BR>

<A HREF="page_2.php<?print("?letter=a");?>" TARGET="iframe1">Link</A><BR>
<A HREF="page_2.php<?print("?letter=b");?>" TARGET="iframe1">Link</A><BR>
<A HREF="page_2.php<?print("?letter=c");?>" TARGET="iframe1">Link</A><BR>
<iframe id="gframe" name="iframe1" marginwidth=0 marginheight=0 frameborder=1 vspace=0 hspace=0 border=1 src="page_2.php" width=100% height=100%>
</iframe>

The iframe is what im having problems with but heres the main page so you can see better what im trying to say. so please help me with the iframe.

Now I want so that when you click a link it will say what letter/number it is, then click the other one ( letter or number depending which you clicked ) and it will say the letter that was last clicked and the number last clicked, so i could click a, then 2, and it would display a, then when i clicked 2 it would display a, 2, then when i click b it would display b, 2.

sorry if this is kind of vague 🙂

Thanks!

I can't immediatly think of any other better way than sessions or cookies. I'll use sessions since I like them more 🙂.

This example will require php 4.1.*

Try this for page_2.php

//start the session
session_start();

//See what needs to change
if (isset($_GET['number'])) {
    $_SESSION['number'] = $_GET['number'];
}
if (isset($_GET['letter'])) {
    $_SESSION['letter'] = $_GET['letter'];
}

//display it
echo "$_SESSION[letter], $_SESSION[number]";

That didnt work... 🙁 😕
Try running the page on your computer with the code
below, test it out and stuff cause it just dont work 😕

The Main Page. (start.php)

print("<A HREF=\"iframe.php?letter=a\" TARGET=\"iframe1\">A</A> - ");
print("<A HREF=\"iframe.php?letter=B\" TARGET=\"iframe1\">B</A> - ");
print("<A HREF=\"games.php?number=1\" TARGET=\"iframe1\">1</A> - ");
print("<A HREF=\"games.php?number=2\" TARGET=\"iframe1\">2</A> - ");
<iframe id="gframe" name="iframe1" marginwidth=0 marginheight=0 frameborder=1 vspace=0 hspace=0 border=1 src="games.php<?print("?letter=$letter&number=$number");?>" width=100% height=100%>
	Your browser doesn't support the &lt;iframe&gt; tag.  If you want to 
	view the list of games that match your selection while you browse, you 
	can you the <a href="/browse/games/c,1/?o=2&nif=1">non iframe version game browser</a>.</p>
	<p>Internet Explorer 4.0 or higher, Netscape 6, Mozilla and Opera 5 all 
	support iframes, you might consider upgrading to a newer browser.
	</iframe>

The iframe. (iframe.php)

<HTML>

	<TITLE>Clan Quick Silver</TITLE>
	<LINK REL="stylesheet" HREF="../mystylesheet.css">
	</HEAD>
	<BODY>
	<FONT CLASS="medium">
	<UL TYPE="filled">
	<?
                       //start the session
session_start();

//See what needs to change
if (isset($_GET['number'])) {
    $_SESSION['number'] = $_GET['number'];
}
if (isset($_GET['letter'])) {
    $_SESSION['letter'] = $_GET['letter'];
}

//display it
echo "$_SESSION[letter], $_SESSION[number]";

?>
</UL>
</FONT>
</BODY>
</HTML>

please try this out, if you find whats wrong lol ill be happy to let you laugh at me
😃

Thanks

mjlively

Simple problem 🙂
For reasons I won't bore you with, the function [man]session_start/man has to be called before any output is sent to the browser...so if you move that section of code to the top of your page all should be well....try this:

<?php
                       //start the session
session_start();

//See what needs to change
if (isset($_GET['number'])) {
    $_SESSION['number'] = $_GET['number'];
}
if (isset($_GET['letter'])) {
    $_SESSION['letter'] = $_GET['letter'];
}
?><HTML>
    <HEAD>
    <TITLE>Clan Quick Silver</TITLE>
    <LINK REL="stylesheet" HREF="../mystylesheet.css">
    </HEAD>
    <BODY>
    <FONT CLASS="medium">
    <UL TYPE="filled">
    <?php

//display it
echo "$_SESSION[letter], $_SESSION[number]";

?>
</UL>
</FONT>
</BODY>
</HTML>

Could you tell me what error you are getting?

PHPGuru_2700

when I click A it says A, where it should, but when I click 1 it just says ,1 not A, 1, do I have to load a module for sessions or something?

mjlively

You're right, your sessions module may not be loaded. Do you know which version of PHP you're running?

I'm going to be away from my computer for a while but I'll get back with you when I return.

In the meantime try checking out Session handling functions at php.net

PHPGuru_2700

Thanks!
Im Running PHP 4.2.3 And I Read What It Had To Say (it said no changes had to be made to run sessions!) and was no further tell i saw a warning 50 million lines down.... it said
Warning!
with windows users you will have to change the sessions.save.path: from /tmp to c:/tmp
LOL!
Thanks for telling me about sessions and sorry for being a pain

(when you said you where going to bed I thought maybe I'd
given you a headache 😃)

Thanks!!!!!!
